Agenda
● Project Background● Problem Statement & Project
Deliverables● Use Scenarios● Benchmarking of other testers● Prioritized Needs● Engineering Requirements● Draft of Project Plans
Team 14026 – Sept 12, 2013
What is a PEV?
● Portable Emergency Ventilator that provides positive pressure to a person that is incapable of breathing on their own.
Team 14026 – Sept 12, 2013
Previous PEV Prototypes
● MEDIRESP III○ Portable ventilator that does not use an
oxygen tank○ 4 modes of air flow
● MEDIRESP IV○ A digital system
● MEDIRESP V○ Attempting to make it lighter, more compact,
and user friendly
Team 14026 – Sept 12, 2013
Problem Statement● Current State
○ 1st generation of a verification system● Desired State
○ Simulate the respiratory system and measure flow, pressure, volume, and oxygen concentration
● Project Goals/Opportunities○ Collect data to evaluate PEV prototypes○ Develop database of analytic results
● Constraints○ ANSI Z79.7 - Standards for Breathing
Machines for Medical Use○ ISO 5469:1967 - Adult lung and Infant lung○ ASTM F 1100-90 - Ventilators Intended for
Use in Critical CareTeam 14026 – Sept 12, 2013
Project Deliverables
● Functional test fixture that simulates an active lung
● Test data verifying operation● Design alternatives:
○ Calibration techniques

Team 14026 – Sept 12, 2013
Use Scenarios Considered
● Scenario 1: To test the prototypes of the different PEV’s
● Scenario 2: Potential use for quality control in a manufacturing setting
Team 14026 – Sept 12, 2013
Benchmarking Other Testers● CITREX H4
○ mobile & useful for production plants○ completely digital
● FlowAnalyser PF-300○ measures PEEP and peak pressures○ more bulky than CITREX but also more
powerful○ $7650
● Certifier FA Plus Ventilator Test System 4080○ measures air, O2 , Air/O2 mixture,N2,CO2, and
N2O○ neonatal to adult, and high frequency
breathing○ $3465

Preliminary Schedule
Team 14026 – Sept 12, 2013
Issues & Corrective Actions
● Research respiratory system in depth○ Meet with Dr Doolittle
■ Planned meeting on Friday, Sept 20○ Library & Literature Research
■ Books from Risa Robinson■ Keep open communication with Mr
Hanzlik for standards research● Develop Work Breakdown Structure
o Determine strengths of team memberso Determine subsections of project
development● Develop Risk Management
o Develop FMEA tableTeam 14026 – Sept 12, 2013
